Which feature would be best for understanding historical spending patterns in Oracle Cloud?

The Cost Analysis Report is the most suitable feature for understanding historical spending patterns in Oracle Cloud. This report provides detailed insights into spending trends over time, allowing users to analyze costs by various dimensions, such as service types, resources, and time periods. By leveraging this tool, users can effectively track their spending patterns, identify areas of overspending, and make informed decisions to optimize future budgets based on historical data.

In contrast, Budget Management primarily focuses on setting and managing budgets rather than analyzing past spending. While it can help in monitoring current expenditures against set budgets, it does not provide the in-depth historical analysis that the Cost Analysis Report offers. Usage Reports give insights into resource consumption, but they do not explicitly outline spending patterns, making them less relevant for understanding historical costs. Forecast Modelling is geared towards predicting future spending based on trends but does not provide a retrospective look at past expenses, which is crucial for understanding historical patterns.
